Custom runtime module errors (#3433)

* srml-system checks * wip * more modules compiles * node-runtime checks * build.sh passes * include dispatch error in failed event * revert some unnecessary changes * refactor based on comments * more compile error fixes * avoid unnecessary into * reorder code * fixes some tests * manually implement encode & decode to avoid i8 workaround * more test fixes * more fixes * more error fixes * Apply suggestions from code review Co-Authored-By: Tomasz Drwięga <tomusdrw@users.noreply.github.com> * address comments * test for DispatchError encoding * tyep alias for democracy * make error printable * line width * fix balances tests * fix executive test * fix system tests * bump version * ensure consistent method signature * Apply suggestions from code review Co-Authored-By: Gavin Wood <github@gavwood.com> * changes based on review * Add issue number for TODOs * fix * line width * fix test * Update core/sr-primitives/src/lib.rs Co-Authored-By: Bastian Köcher <bkchr@users.noreply.github.com> * Update core/sr-primitives/src/traits.rs Co-Authored-By: Bastian Köcher <bkchr@users.noreply.github.com> * Update srml/council/src/motions.rs Co-Authored-By: Bastian Köcher <bkchr@users.noreply.github.com> * Update srml/council/src/motions.rs Co-Authored-By: Bastian Köcher <bkchr@users.noreply.github.com> * update based on review * More concrete macro matching * fix test build issue * Update hex-literal dependency version. (#3141) * Update hex-literal dep version. * Update lock file. * Start to rework the new error handling * More work to get it back compiling * Start to fix after master merge * The great transaction error handling refactoring * Make `decl_error` errors convertible to `&'static str` * Make srml-executive build again * Fix `sr-primitives` tests * More fixes * Last round of fix ups * Fix build * Fix build * Apply suggestions from code review Co-Authored-By: Tomasz Drwięga <tomusdrw@users.noreply.github.com> * Rename some stuff * Fixes after master merge * Adds `CheckBlockGasLimit` signed extension * Remove debug stuff * Fix srml-balances test * Rename `InvalidIndex` to `CannotLookup` * Remove weird generic parameters * Rename function again * Fix import * Document the signed extension * Change from `Into` to `From` * Update srml/contracts/src/lib.rs Co-Authored-By: Sergei Pepyakin <sergei@parity.io> * Fix compilation * Update srml/contracts/src/lib.rs Co-Authored-By: Tomasz Drwięga <tomusdrw@users.noreply.github.com> * Update core/sr-primitives/src/transaction_validity.rs Co-Authored-By: Tomasz Drwięga <tomusdrw@users.noreply.github.com> * Remove unused code * Fix compilation * Some cleanups * Fix compile errors * Make `TransactionValidity` a `Result` * Apply suggestions from code review Co-Authored-By: Gavin Wood <gavin@parity.io> * Beautify the code a little bit and fix test * Make `CannotLookup` an inherent error declared by `decl_error!` * Adds some documentation * Make `ApplyOutcome` a result * Up the spec_version * Apply suggestions from code review Co-Authored-By: Gavin Wood <gavin@parity.io> Co-Authored-By: DemiMarie-parity <48690212+DemiMarie-parity@users.noreply.github.com>
